Abstract
An electrical clamp assembly of the type for securing electrical conductive elements to an electrical device, such as an electrical terminal, comprises an interconnected clamping plate and screw. Bearing surfaces between the clamping plate and screw head comprise an anti-friction ball joint. The ball joint provides a means for converting the entire amount of tightening-torque applied to the screw head to substantially an equivalent amount of clamping force at a clamping surface of the plate by minimizing frictional resistance between the bearing surfaces. A race-like portion of the ball joint also provides a means for inseparably holding the plate about an unthreaded portion of a partially threaded screw shank without allowing the plate to harmfully abuttingly interfere with the threads of the screw. A plurality of ribs are disposed on the bottom surface of the plate to form a rhombus-like pattern and to prevent lateral slipping of the conductive wire during torquing of the screw.
